Pittsburgh averages 60 to 70 percent relative humidity during summer months, forcing air conditioners to remove moisture and cool air simultaneously. This dual load increases runtime and stresses compressors, evaporator coils, and blower motors. Sudden temperature drops during evening thunderstorms cause rapid pressure changes in refrigerant lines, accelerating wear on expansion valves and compressor seals. Homes near the Allegheny, Monongahela, and Ohio rivers experience even higher humidity levels that promote evaporator coil corrosion and condensate drain clogs. Emergency air conditioning repair calls spike during heat advisories when systems run continuously without rest periods.
